The purpose of this study was to examine the effects of display on time on tasks and virtual presence in the immersive virtual reality. Head mounted display (HMD) and monitor conditions were compared when the participants were asked to complete navigation tasks in a virtual classroom. Time on tasks and virtual presence were measured. Three factors of the virtual presence were applied as dependent variables such as 1) spatial presence, 2) involvement, and 3) realness. The results showed that HMD condition took longer time to finish tasks than monitor conditions. HMD condition showed significantly higher perception from all of the virtual presence factors. Interestingly, there was a significant interaction effect between the display conditions and presence factors. The relationship between display types and virtual presence factors were discussed for future study.

가상환경에서의 실재감을 증대시키는 방법 중에 하나는 상호작용을 이용하는 방법이다. 즉, 사용자가 가상환경에 변화를 줄 수 있게 하여, 사용자와 가상환경 사이의 결속감을 통해, 사용자가 가상환경 속에 있는 듯한 느낌을 주는 것이다. 그러나, Architectural Walkthrough 혹은 Navigation 시스템은 기능적으로 가상객체와에 affordance 와 그 밖의 interactivity cue를 적용하여 사용자로 하여금 시각적으로만 상호작용감을 유발하게 하여, 사용자의 실재감을 높이기 위한 방법에 대한 것이다. 두 개의 가상환경에 대하여 아무런 visual cue가 없는 경우, 텍스트를 이용한 직접 표현 방법, 객체가 simulation 된 trace 그리고 affordance cue 등 총 4가지 방법들, 즉 총 8가지 실험 조합에서 사용자가 느끼는 상호작용성과 실재감을 측정하였는데 interactivity유도를 위한 간접적인 visual cue가 쓰였을 경우 통계적으로 유의하게 상호작용성 및 실재감이 증대하는 결과를 보여주었다. 이는 적은 모델링만의 노력으로, 실제 인터액션에 대한 구현 없이 가상환경에서 어느 정도의 실재감을 높일 수 있는 방법을 제시하고 있다.

There have been many experiments and researches of virtual marionettes which mostly focused on controlling the marionettes more delicately and precisely. This paper will prove that performances using virtual marionettes can show more than simply controlling other objects delicately and precisely. The performance that this paper is discussing about used not only a virtual marionette but also an actual marionette. In this performance, a human manipulated an actual marionette and the actual marionette controlled a virtual marionette. This performance is meant to represent a controlling relationship between an actual world and a virtual world. This recursive and duplicate process will show that experiments using virtual marionettes can express more diverse objectives than existing experiments.

Images of TV that crossed the reality & the virtual reality have been discussed for a long time, Then, With what feature can TV make messages of the reality & the virtual reality maintain to achieve such a target, and in which situation will the feature be exposed? One who answered first about these questions is a German critic, G$\ddot{u}$nter Anders. Anders called the reality confused with the reality and the confused world of the virtual reality Phantom, and thought human beings would live in the reproduced world created by media machine in the long run as a world that the Phantom created would be gloomy and confusing. The media, themselves, become images, and an image creates another image. Through this process, human beings became unaware of which image the reality was indeed. As TV often created these situations, we have been already seduced into the deep Phantom world before discussing right or wrong of the situation. Of course, the media reality & the reality can't be strictly distinguished. Because the means that help to form judgement of viewers is the media. The subject of practical judgement is the media reality not human beings.

Backed by the fourth industrial revolution as the background of the research, VR, AR and MR have increased interest and wireless Oculus Quest is releasing, creating hardware recall and continuing virtual reality devices, and game software develop or service VR games using such devices. As a result, it is expected that VR game markets will continue to grow in the future. For this purpose, we understand the technical factors of presence and immersion that appear in virtual reality games and should be able to apply them when we produce VR games. Through the process, we analyzed elements of VR game concept, immersion, and presence and analyzed three games that were commercialized. As a suggestion, we need to take into account presence and immersion characteristics when developing and experiencing virtual reality games in the future.

본 연구는 뉴미디어 환경에서 맥퀘일이 제시한 대안적 커뮤니케이션의 3 가지 양식인 전달(transmission)모델, 표현적(expressive) 또는 의식적(ritual)모델, 주의력(attention)모델이 어떻게 나타나고 있는지 게임형 가상세계 <월드 오브 워크래프트>의 사례를 중심으로 살펴보았다. 또한 이와 함께, 상호작용성과 사회적 실재감이 어떻게 구현되고 있는지를 분석했다. 연구 철과 대안적 커뮤니케이션 양식은 게임형 가상세계라는 뉴미디어 환경에서도 여전히 유효하며 다양한 사례를 통해 검증되었다. 또한 상호작용성과 실재감은 게임형 가상세계의 중요한 특징을 이루며 수용자들의 몰입과 적극적 참여를 높이는 기재로 작동하였다.

In this study, we experimented with experience of digital signage using Virtual Reality technology, and the difference between presence and interactivity in brand experience and digital signage attitude. We conducted a two-way MANOVA analysis with cognitive presence, emotional presence, and media presence as the independent variable and interactivity level(high vs low) as dependent variables and the brand experience and attitude as dependent variables. First, cognitive presence was found to be most effective through behavioral experience when low interactivity. Second, emotional presence also has a positive effect on emotional experience when the level of interactivity is low. Third, media presence has a positive effect on emotional experience if the level of interactivity is low. This study suggests a communication strategy to communicate presence according to the characteristics of media strategy and technology through appropriate level of interactivity when using digital technology. Future research requires a qualitative approach rather than a quantitative one in terms of interactivity.

This study investigated an evolutionary process of In-game Animation and researched on the action of realization establishing virtual reality. In-game Animation, functioning as contents to visualize games, is responsible for conveying information to achieve goals of games. In-game Animation which is affected by graphic technology was initiated with setting up indicators by dot and line. Followed by the development of technology, In-game Animation has pursued realization, after passing through processes of iconography, materialization, and dimensionalization. The realization of In-game Animation does not simply imitate the real world but creates meaning of reality by establishing space with various factors such as characters and background along with the story, under the premise of virtuality. The realization of In-game Animation is very important to provide the experience of immersion, as it forms a sense of presence through such visual tactility. The process to create meaning of reality provides gamers with experiences, and leads them to expand senses through visual perception and finally absorb the virtuality as reality. Therefore, the image of In-game Animation does not simply imitate the real world but creates meaning of reality by establishing space with various factors such as characters and background along with the story, under the premise of virtuality. The realization of In-game Animation is not limited to blindly portray a realistic image. In addition, the process of realization pursued by In-game Animation is an action to immerse in the game rather than a mere product of technological development.

This study investigated how presence will affect the user's trust in educational serious game. To achieve our research purposes, we divide presence into two parts: virtual presence and social presence and identify the relationship between trust and trustworthiness. and also, we separate out trust such as trust in learning and trust in fun according to users purposes. We conduct the survey using the english serious game for university student. The results show that presence significantly influence on trustworthiness and also trustworthiness effect on trust in learning and fun.

민첩생산의 필요성이 날로 증가하고 있는 생산환경 하에서 대표적인 자동생산시스템인 FMS의 효율적인 운영과 동시에 원격지에서의 FMS 모니터링 및 제어는 필수화되고 있다. 최근에 시뮬레이션을 기반으로 하는 가상생산의 개념이 일반화되고 이를 지원하는 다양한 정보기술의 발전에 따라 FMS에도 적용되고 있다. 본 논문에서는 웹환경 하에서 실재 FMS와 이에 대응되는 가상 FMS를 통합함으로서 원격지에서의 효율적 운영을 지원하는 모니터링 및 제어시스템 구축방법을 소개하고자 한다. 또한 키트형 FMS와 이에 대한 가상 FMS 모델를 대상하여 적용한 결과를 소개하도록 한다.
